These ingredients are thoroughly mixed together, and the use of the resulting compound produces very satisfactory results for the clarification of water and thereinoval and prevention of incrustation from bollers;

Very good results may be obtained from a mixture of flaxseed and glue, barley-sprouts 3 5 and glue, flaxseed and barley-sprouts, or flaxseed mixed wit-h water.

Having fully described my invention,what I 4 5
